Question

Велосипидист и мотоциклист начали движение одновременно в одном и томже напровлении. Скорость велосипидиста 17 км/ч скорость мотоциклиста в 5 раз больше. На сколько километров мотоциклист обгонит велосепидиста за 2 часа

Answer 1

(17•5)-17=68 км/ч скорость отдаления.
68•2=136 км между ними через 2 часа.
Всё!

Answer 2

17*5 85
85*2-17*2
170-34=136 км

Answer 3

Problem Analysis

We are given that a cyclist and a motorcyclist start moving simultaneously in the same direction. The cyclist's speed is 17 km/h, while the motorcyclist's speed is 5 times greater. We need to determine how many kilometers the motorcyclist will overtake the cyclist in 2 hours.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by the cyclist and the motorcyclist in 2 hours.

The cyclist's speed is 17 km/h, so in 2 hours, the cyclist will travel:

Distance_cyclist = Speed_cyclist × Time = 17 km/h × 2 h = 34 km The motorcyclist's speed is 5 times greater than the cyclist's speed, so the motorcyclist's speed is:

Speed_motorcyclist = 5 × Speed_cyclist = 5 × 17 km/h = 85 km/h

In 2 hours, the motorcyclist will travel:

Distance_motorcyclist = Speed_motorcyclist × Time = 85 km/h × 2 h = 170 km Therefore, the motorcyclist will overtake the cyclist by 170 km - 34 km = 136 km in 2 hours.

Answer

The motorcyclist will overtake the cyclist by 136 kilometers in 2 hours.

Explanation

The cyclist and motorcyclist start moving simultaneously in the same direction. The motorcyclist's speed is 5 times greater than the cyclist's speed. Therefore, the motorcyclist will cover a greater distance in the same amount of time, resulting in an overtake. In this case, the motorcyclist will overtake the cyclist by 136 kilometers in 2 hours.
